Incident spectral solar irradiance measured above sea ice at station ALERT2018_22_1@en

Measurements of solar radiation over sea ice have been performed on First-Year-Ice (FYI) and Multi-Year-Ice (MYI) during the ALERT2018 campaign (Multidisciplinary Arctic Program (MAP) - Last Ice) off Alert, Nunavut, Canada in the Lincoln Sea between 07 May and 23 May 2018. The radiation measurements have been performed with Ramses spectral radiometers (TriOS, Rastede, Germany). All data are given in full spectral resolution interpolated to 1.0 nm, and integrated over the entire wavelength range (broadband, total: 320 to 950 nm). The irradiance sensor (cos-collector) was installed on the sea ice for surface reference measurements (solar irradiance). All times are given in UTC.

本数据集基于2018年5月7日至5月23日于加拿大努纳武特地区阿勒特附近林肯海海域开展的ALERT2018科考计划（多学科北极计划（Multidisciplinary Arctic Program, MAP）- 最后冰区），针对一年冰（First-Year-Ice, FYI）与多年冰（Multi-Year-Ice, MYI）完成了海冰上方的太阳辐射测量。本次辐射测量采用德国拉施泰德TriOS公司生产的Ramses光谱辐射计进行。所有数据均保留原始全光谱分辨率，经插值至1.0 nm步长后，在全波长范围（宽带总辐照度：320 nm至950 nm）内完成积分。辐照度传感器（余弦收集器，cos-collector）被安装于海冰表面，用于开展太阳辐照度的地表参考测量。所有时间均采用协调世界时（UTC）标注。
